Just heard about this, again via CISA. Sign up for the Pioneer Valley Heritage Grain CSA, organized by Wheatberry Farm and Bakery with the participation of multiple Valley Farms, and get 100 pounds of heritage grains and dry beans.
A full share costs $350. A half share, about 50 pounds, costs $200. There are two pick-up dates in November, at farms in Hadley and Shutesbury, and shareholders must show up at both to get the whole share. The grains are unmilled (i.e. whole grain, not flour) but milling is available weekdays at Wheatberry Farm or you can use a home flour mill like I have.
See the website for details and the sign-up form.
(If 100 lbs, or even 50 lbs, sounds like too much at once, there are a few other sources of local grain and flour in the Valley, including Four Star Farms in Northfield and Upinngil Farm in Gill. I have seen Four Star Farms at Winter Fare and other markets, and Upinngil has a farm stand that is open year round.
